Anker has released two officially licensed power banks/portable chargers for the Switch in Japan. There's the Anker PowerCore 13,400 Nintendo Switch Edition (priced at ¥6,980) and the Anker PowerCore 20,100 Nintendo Switch Edition (priced at ¥9,980).
Both of them include a pouch and USB cable.

The latest bit of software from Switch hackers is LayeredFS, a program that lets people add in/replace chunks of data in games. In other words, you can add in cheats, new character models, text, and some other things as well. In the clip above, you can see someone has thrown in a whole bunch of cheat spells into Skyrim.
